General Description

The A80804 and A80804-1 are linear, programmable current controllers capable of accurately regulating current in four LED strings using external MOSFETs.

Each of the four LED drivers has an independent enable/PWM input and current-sense resistors and can be independently dimmed with an external PWM signal, or all channels can be dimmed with internal PWM dimming and automatic phase shifting.

The overall LED current can be switched between low and full intensity for applications including stop/tail or DRL/position lighting.

Overview
